A ton of oyster shells for 5,000 yuan?
The Japanese front foot high-priced recycling of "discarded cigarette butts", the American back foot will smell the sound, high-priced recycling of "oyster shell", are you curious, what is the use of oyster shells? Clams are also the oysters in everyone's mouth, because of their delicious taste and cheap price, they are loved by barbecue lovers, and I believe that no one except people who are allergic to seafood can resist its temptation. After eating the oysters, how are the oyster shells handled?
Hearing this, many people will feel inexplicable, it must be thrown away, how can it be handled, is it difficult to make crafts and hang at home? The citizens of New York, USA, did not make crafts, but brought it home, and after they ate the oysters, they would pack the oyster shells and take them home, save a certain amount and sell them to recyclers at a high price.
A ton of oyster shells in New York, USA, can even sell for a high price of 5,000 yuan, yes, you heard it right. The most bizarre thing is that they do not make oyster shells into crafts, but directly into the sea, what are the Americans for?
Oysters are bivalve molluscs
Before answering this question, let's get to know oysters. Why does it stand out from many seafood and become the "hegemon" of the night market? As the only shellfish that can be eaten raw, it has a very high status in Japan and is known as the "source of roots".
Oysters, also known as oysters, also known as sea oysters, oysters, oysters, oval bodies, and two-sided shells, living in temperate and tropical waters along the oceanic coast. There are more than 100 species of oysters in the world, and about 20 species are produced along the coast of the mainland.
Flocks of oysters are everywhere along the seashore, and the shells are very hard and sharp. Oysters as a common economic type of shellfish, from ancient times and there have been records of eating oysters and raising oysters, the Han Dynasty "bamboo planting to raise oysters"
Quite a few people
They are all fond of oysters, and his delicacies have even inspired many creators, once describing the appearance of the upper class people eating oysters in Maupassant's "My Uncle Hule" in the primary school textbook, and just reading the text makes the population flow. Li Bai also wrote an inscription that reads, "Heaven and earth, oysters are exclusive."
Oysters can be eaten raw or cooked. The most common oyster oyster practice in ordinary life today is garlic oysters. Imagine putting milky oyster meat on a grill, the umami taste of oysters being roasted, drizzled with some minced garlic, and slowly feeding it into your mouth, feeling the ultimate umami in your mouth.
Oyster meat can provide us with rich nutrition, it is rich in protein and trace elements necessary for the human body. Other than that. Oysters have also been called "women's beauty salon, men's gas station" is also a certain reason, but also does have the effect of beauty and beauty. Moreover, in Traditional Chinese medicine, oyster shells can be medicated, which can play a role in calming the nerves and helping sleep.
Americans do not believe in Chinese medicine, let alone eat Chinese medicine, Chinese medicine for foreigners, is simply a dark dish. So Americans must not be directed at the "medicinal value" of oyster shells. Back to the original question, why did Americans throw oyster shells into the sea after they recycled oyster shells at high prices, and what purpose did they have?
The United States is a oyster country, New York is known as the "Oyster Capital", New York Harbor once had about 200,000 acres of oyster reefs hundreds of seven years ago, billions of oysters accounted for half of the world's population. People have just learned that oysters can be eaten, because oysters are abundant and affordable, and the streets and alleys are everywhere, and the citizens of New York have begun to eat oysters in large quantities.
According to incomplete statistics, the average New Yorker can eat more than 600 oysters per person per year, which is 6 times that of the British. In downtown New York at that time, "oysters were everywhere" and "six points to eat." The chef has more than 150 pages of oyster recipes.
All over the world, whether it is China or abroad, oysters are favored, but the types of oysters raised in different seas are not the same, and there are great differences in eating methods between the East and the West, Europe prefers raw food, paying attention to "open shell and eat", China likes to eat after cooking, grilling, frying, making cakes, stir-frying, etc.
The situation on the mainland is better, as early as 2,000 years ago, it mastered the oyster culture technology, and now the technology is more mature, as early as 2017, the production of artificially farmed oysters on the mainland has fully met the domestic market demand.
No matter how many oysters there are, they can't help but eat like this. If you eat it at this rate, oysters are about to be eaten as protected animals, and the number of oysters in New York is indeed decreasing significantly.
With the rise of the Industrial Revolution, industrial wastewater has slowly polluted the river, the water quality in New York, the United States is getting worse and worse, the "oyster country" has gone downhill, and the oyster era is gradually approaching the end, but why is the poorer the water quality, the less the number of oysters?
What role can the "oyster shell" that Americans throw directly into the sea play?
It is important to know that oysters are natural purifiers, although small, but can purify a lot of seawater, an adult oyster, can purify about 190 liters of seawater per day. In addition, the reef area formed by oyster swarms can also provide habitat for seals, dolphins, etc., stabilizing ecosystems and biodiversity.
Do you think that a large number of oysters are only cultivated to solve water quality problems? No, oysters can be a natural breakwater in addition to eating and purifying water quality. New York is located on the east coast of the United States, and typhoons come every three to five minutes, because without the protection of the reef embankment, the typhoon may pose a threat to the lives and property of New Yorkers.
In order to reduce the damage of the hurricane, New York had to rebuild an oyster reef embankment, and after recognizing the problem, there was a public welfare team that launched a "billion oysters project" that planned to restore the number of oysters to its former peak.
As oyster seedlings were thrown into the sea in large quantities, gradually there was a problem in front of the Americans. The growth rate of oyster seedlings is too slow, and it is not known how long it will take to build a reef embankment. After much consideration, the Americans finally decided to recycle the used oyster shells, put the cultivated oyster seedlings in it, and once again put them into the ocean. The oyster shells are attached to more and more wild oysters, slowly forming a reef embankment, and the reality is indeed what they wished.
Instead of becoming a delicacy on the table, as they once did, these oysters shield New Yorkers from the storm and improve the water quality in the ocean. I have to say that this is really a good thing to kill two birds with one stone, what do you think about this? Stay tuned for the next issue, click to follow and go!
